The Dow Jones Industrial Average — whose climb this year was cited by President Donald Trump as evidence of his policies’ economic effectiveness — has turned negative for the year as the ongoing conflict between the US and Iran weighed on investor sentiment.

The index, comprised of well-known names such as JPMorgan Chase & Co., Coca-Cola Co. and Boeing Co., slumped 1.6% on Thursday as energy prices soared. Goldman Sachs Group Inc., Caterpillar Inc. and Walmart Inc. were among the gauge’s biggest decliners. The average is now down 0.2% year-to-date.
